Jenna Coleman Confirms "Doctor Who" Departure

On the eve of “Doctor Who’s” Series 9 premiere, Jenna Coleman has official announced that she’s leaving the popular BBC drama.

“I have left the TARDIS — it’s happened,” she told BBC Radio 1 this morning. “”I’ve filmed my last scenes.”

Coleman joined the show in March 2012 as the Doctor's new companion Clara Oswald. She actually made her “Doctor Who” debut in the Series 7 premiere, where she playedOswin Oswald. The actress, who’s starred opposite both Matt Smith and Peter Capaldi, didn’t reveal just when Clara will exit the series.

“It’s been in the works for a very long time,” Coleman said. “Steven [Moffat] and I sat down a year and a half ago and tried to work out the best place to do it and tell a really good story. “We’re not going to give any details but it will happen at some point this season. … We worked out a really good story arc out so hopefully people will love it.”

Clara is a companion with a bit of convoluted history. Her first appearance might be in "Asylum of the Daleks" or "The Snowmen" or "The Bells of St. John." We found out last series that Clara managed to jump into the Doctor's timeline to save him from the Great Intelligence. This ended up splitting her across time, and makes it very difficult to pin down when she first meets the Doctor.

With Clara returning for Series 9, she will become the longest serving companion.
